Using it's concept, it is found that due to the lowest Mean Absolute Deviation, his scores were closest together in Math.

What is the mean absolute deviation of a data-set?

  • The mean of a data-set is given by the sum of all observations divided by the number of observations.
  • The mean absolute deviation(MAD) of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
  • The mean absolute deviation represents the average by which the values differ from the mean. Hence, lower values of the MAD means that the distribution is closer together.

Of the four classes, Math was the lower MAD, hence it has the scores that are closest together.
